Open circuit and short circuit What is an Open Circuit? | An open circuit means there is a break or gap in the path where electricity should flow. Imagine a road where a bridge is broken — cars can’t pass through it. In the same way, when a wire or part of the circuit is … Read more
Introduction to Magnetic Circuits We all know that magnets can pull things like pins or nails. But have you ever wondered how this invisible pull works inside machines like fans, motors, or transformers? Well, it’s all about something called a magnetic circuit. Just like electric current flows in a loop through wires in an electric … Read more
Magnetic Hysteresis When we take a piece of magnetic material—like iron—and magnetise it first in one direction, and then in the opposite direction, something interesting happens. The magnetic strength inside the material does not follow the applied force exactly. Instead, it lags behind. This delay is called Magnetic Hysteresis. 🔄 What is Magnetic Hysteresis? Magnetic … Read more
Magnetic Flux Density Have you ever seen how magnets pull things without touching them? This invisible force spreads out in space like magic. But how do we measure this magnetic power in a certain area? That’s where Magnetic Flux Density comes in. 🌟 What is Magnetic Flux Density? Magnetic Flux Density is a way to … Read more
Definition of Parallel Plate Capacitor A parallel plate capacitor is a device made of two flat, conductive plates placed parallel to each other with a small gap between them. This gap is usually filled with air or a material called a dielectric. When we connect a battery or voltage source across the plates, one plate … Read more
what is magnetism? Long ago, people thought magnetism was a kind of magic. They didn’t understand how it worked, so they didn’t use it much. But as time passed and science grew, we learned the truth — magnetism is not magic, it’s a real and powerful force. Today, magnetism is one of the most important … Read more
Introduction to Capacitors: We all know that different objects can hold different amounts of electric charge, even when they are at the same voltage. This ability to store charge is called capacitance. To store a useful amount of charge, we use a special device called a capacitor. A capacitor is made of two metal plates placed close … Read more
Cylindrical Capacitor A Cylindrical Capacitor consists of two concentric conducting cylinders separated by an insulating dielectric material. The formula gives its capacitance (C): C = (2π ε₀ εᵣ L) / ln(b/a) where: This type of capacitor is widely used in underground and coaxial cables, where the cylindrical geometry provides uniform electric field distribution and efficient … Read more
Capacitors in Series and parallel Let’s imagine you have three capacitors — we’ll call them C₁, C₂, and C₃.Now, we connect them one after another, like links in a chain. This is called a series connection. When we apply a voltage V across this whole chain, something interesting happens: Now, remember a simple rule:Q … Read more
